Do you know how to configure GPON FTTH Layer 2 Internet Access Service on the NMS?

Services can be configured for an Huawei ONT HG8245H only after the ONT is successfully added to an OLT.

Networking

• The PC gains access to the Internet in PPPoE dialup mode.
• The ONT is connected to the GPBC card of the OLT through an optical fiber.
• The broadband remote access server (BRAS) provides broadband user access and functions of authentication and accounting.

Configuring the GPON FTTH Internet service 

Procedure

 NOTE:

After all profiles are configured, perform the following steps to issue them to the device:

• In the information list, right-click the record and choose Download to NE from the shortcut menu.
• In the dialog box that is displayed, select the required NE(s), and click OK.

1, Configure a DBA profile.

2, Configure a line profile.

In a line profile, a GEM port can be bound to up to eight service streams. In a GEM port, different GEM connections need to be set up for different service streams.

In this example, the mapping between GEM ports and ONT-side services is implemented through VLANs, and the service streams of each service are mapped to GEM port 14. In addition, different GEM connections are set up for the management VLAN and the VLANs for the Internet, voice, and multicast services.

3, Configure a service profile.

Set the port capability set to adaptive. Then, the system adapts the port capability set of an online ONT to its actual capability. Then, in the ONT service profile, configure a VLAN translation policy to translate C-VLAN 1001 to VLAN 100.

4, Configure an MEF IP traffic profile.

The profile name is ftth_hsi, CIR is 4 Mbit/s, and the priority is 0. Traffic is scheduled based on the priority specified in the profile.

5, Configure a service VLAN on the OLT MA5600T side.

The prerequisite for performing operations in the navigation tree is to navigate to the NE Explorer of the OLT. To navigate to the NE Explorer of the OLT, do as follows: In the Main Topology, double-click the required OLT in the Physical Root navigation tree; or right-click the required OLT and choose NE Explorer from the shortcut menu.

A service VLAN is the VLAN used for the Internet service.

The prerequisite for performing operations in the navigation tree is to navigate to the NE Explorer of the OLT. To navigate to the NE Explorer of the OLT, do as follows: In the Main Topology, double-click the required OLT in the Physical Root navigation tree; or right-click the required OLT and choose NE Explorer from the shortcut menu.

1. Add an ONT.
   The ONT connects to the GPON port 0/1/0 is ONT 1. The serial number of the ONT is 32303131D659FD40, password is 0100000001, discovery mode for password authentication is once-on, management mode is OMCI, bound ONT line profile name is ftth, and the ONT service profile name is ftth.
2. Configure an ETH port of Huawei GPON ONU.
3. Add a service virtual port on the OLT side.

Result

Check whether the user successfully gains access to the Internet through dialup on the PC.

1. The LAN1 port of the ONT is connected to the Ethernet port of the PC properly.
2. Dial up on the PC using the PPPoE dialup software.
3. The user gains access to the Internet on the PC after the dialup is successful.

How to Query Traffic of a Port on Huawei MA5616?

How to Query Traffic of a Port on Huawei MA5616?

On current ONUs, you can query packet statistics of a port but cannot directly query traffic of a port. To obtain traffic of a port, you can collect the number of frames received or transmitted by the port in a period of time as follows:

1. Query the number of frames received or transmitted by a port at two different time points by running the following commands for different scenarios:
   • On a GPON uplink port, run the interface gponnni command to enter the GPONNNI mode, and then run the display gpon-port statistics command to query the number of frames received or transmitted by a port.
   • On other ports, run the display interface [ interface-type [ interface-number ] ] command to query the number of received or transmitted by the ports.
2. Use the following formula to calculate the number of frames received or transmitted by a port between two time points: Number of frames collected the second time - Number of frames collected the first time.
3. Use the following formula to calculate the traffic on the port: Number of frames x Bytes per frame.

For example, the number of frames on a port are collected at two time points within 30s, and the number of frames between the two time points is 85734 (786687061 - 786601327). Assume that the length of a frame is about 1500 bytes. The traffic on the port within 30s is 981 Mbits (85734 x 1500 x 8= 1,028,808,000 bits), or 122.6 Mbytes.

Configuring a GPON ONT Capacity Profile (Distributed Mode)

A GPON ONT capability profile identifies the actual capability of a GPON ONU. After an ONT is added and bound to a Huawei GPON ONT capability profile, the ONU carries the corresponding services according to parameters configured in the capability profile.

Context

All GPON ONUs must be bound to the GPON ONT capability profile. Specify the ONT capability profile when running the ont add command to add an ONU offline or running the ont confirm command to confirm an automatically discovered ONU.

Currently, the system provides seven default ONT capability profiles that are solidified in the system. The default profiles cannot be modified. The default profile IDs range from 1-7. The reserved ONT capability profile IDs are 8-16.

The contents of the capability profile restrict the port number that is used in commands for GEM port mapping, T-CONT/PQ mapping, and the ONT VLAN management.

The ONT capability profile must be configured according to the actual capability of the ONU. Different the capability profile parameters vary according to different ONUs.

Procedure

Step 1 Run the ont-profile add command to configure an ONT HG8546M capability profile.

• When you add an ONT capability profile, if the profile ID is not specified, the system automatically allocates the least idle profile ID; if the profile name is not specified, the system adopts the default name ont-profile_x, where, x is the corresponding ONT capability profile ID.
• The system supports up to 128 ONT capability profiles.
• The system default profiles include the MDU profile and several common ONT (such as OT925, HG850, and HG810) profiles, which can be directly used. It is recommended to manually configure an ONT capability profile only when the default ONT capability profile fails to meet actual requirements.
• When you add an MDU profile manually, the number of the ports must be set to zero.

Step 2  Run the display ont-profile command to query the ONT capability profile.
